The methodology used in the evaluation of this unit is the same as that described in SO 000 433. Again seventy teachers participated along with 2,400 seventh through twelfth grade students. There were eight parts to this unit that were evaluated by the teachers: 1) The Population-Size and Spacing of Urban Settlements in a Region; 2) The Functions of Urban Settlements; 3) The Market Areas of Settlements; 4) Changes in the Urban System Over Time; 5) Interdependence Among Metropolitan Areas; 6) Hierarchy of Metropolitan Areas; 7) Accessibility; and, 8) Inter-Metropolitan Growth. The evaluation of each activity as in the other reports, included: a statement of the concept(s) it hoped to teach, a description of the exercises in each activity, and results of the unit test questions pertaining to that activity. The discussion also included general observations on: the clarity of directions, interest motivation effectiveness, and suggestions for revision based on the unit test results. Many teachers noted great interest in the content of the unit, however, they also felt that the readings and activities were unduly complex and confusing. The unit test and the results, the evaluation forms and the statistics are appended. See SO 000 433 for a list of related reports. (SBE)
